BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a vehicle including a plurality of seats located next to each other in a vehicle width direction.

2. Description of the Related Art

There are known vehicles including a plurality of seats located next to each other in the vehicle width direction and being capable of running on uneven terrain, such as ROVs (Recreational Off-highway Vehicles) and side-by-side ATVs (All Terrain Vehicles). Vehicles running on uneven terrain are required to absorb impacts and damp vibrations while running. Shock absorbers have been used to absorb impacts and damp vibrations in these vehicles.

U.S. Pat. Nos. 7,819,220, 7,278,648 and U.S. Patent Application Publication No. 2011/0048833 disclose vehicles including left and right front wheels, and left and right shock absorbers connected to the left and right front wheels, respectively. These vehicles include a front cover integral with front wheel fenders. The shock absorbers are located under the front cover. The shock absorbers are hidden under the front cover and are not visible when the vehicle is seen from above.

Some vehicles capable of running on uneven terrain are required to have an improved running performance than before. In order to improve the running performance, it is preferred to elongate the stroke of the shock absorbers. Since it is difficult, due to the vehicle layout, to raise the position of the lower end portion of the shock absorber, elongating the stroke requires raising the position of the upper end portion of the shock absorber. Then, it is necessary to locate the front cover at a higher position in order to avoid interference between the upper end portion of the shock absorber and the front cover. On the other hand, vehicles capable of running on uneven terrain are preferred to have a desirable front visibility when climbing up a steep hill, for example. For improved visibility, the position of the front cover is preferably low. With conventional vehicles, however, it has been difficult to improve the front visibility while providing an increased stroke for the shock absorbers of the front wheels.

SUMMARY OF THE INVENTION

Preferred embodiments of the present invention have been made in view of the problems set forth above, and provide a vehicle, such as an ROV, including a plurality of seats located next to each other in the vehicle width direction with which it is possible to provide both an improved stroke for the shock absorbers of the front wheels and an improved front visibility.

A vehicle according to a preferred embodiment of the present invention includes a vehicle body frame; a plurality of seats located next to each other in a vehicle width direction, each of the plurality of seats being supported on the vehicle body frame; a left front wheel located forward of the plurality of seats; a right front wheel located forward of the plurality of seats and to the right of the left front wheel; a left arm extending in the vehicle width direction, the left arm including a wheel connection portion connected to the left front wheel and a frame connection portion pivotally connected to the vehicle body frame; a right arm located to the right of the left arm and extending in the vehicle width direction, the right arm including a wheel connection portion connected to the right front wheel and a frame connection portion pivotally connected to the vehicle body frame; a left shock absorber including an upper end portion pivotally connected to the vehicle body frame, and a lower end portion pivotally connected to the left arm; a right shock absorber located to the right of the left shock absorber, the right shock absorber including an upper end portion pivotally connected to the vehicle body frame and a lower end portion pivotally connected to the right arm; and a front cover located forward of the plurality of seats and located above the left arm, the right arm, the lower end portion of the left shock absorber, and the lower end portion of the right shock absorber. At least one opening is provided in the front cover. The upper end portion of the left shock absorber and the upper end portion of the right shock absorber are located so as to be visible within the at least one opening when the vehicle is seen from above.

With the vehicle set forth above, the upper end portion of the left shock absorber and the upper end portion of the right shock absorber are located so as to be visible within the at least one opening of the front cover when the vehicle is seen from above. Even if the positions of the upper end portions of the shock absorbers are high, or the position of the front cover is low, the upper end portions of the shock absorbers and the front cover will not interfere with each other. Therefore, the positions of the upper end portions of the shock absorbers are raised to provide an improved stroke for the shock absorbers. Moreover, the position of the front cover is able to be lowered to provide improved front visibility. Thus, with the vehicle set forth above, it is possible to provide both an improved stroke for the shock absorbers and an improved front visibility.

According to a preferred embodiment of the present invention, the front cover includes a sloped portion sloping downward toward a front of the vehicle, and a peak portion located at a rear end of the sloped portion. The peak portion of the front cover is located rearward of the upper end portion of the left shock absorber and the upper end portion of the right shock absorber.

With the preferred embodiment set forth above, the upper end portion of the left shock absorber and the upper end portion of the right shock absorber are located forward of the peak portion of the front cover. Even if the positions of the upper end portion of the left shock absorber and the upper end portion of the right shock absorber are high, the portion of the front cover that is forward of the peak portion is a sloped portion sloping downward to the front of the vehicle, thus providing an improved front visibility.

According to another preferred embodiment of the present invention, the front cover includes a sloped portion sloping downward toward the front of the vehicle, and a peak portion located at a rear end of the sloped portion. The at least one opening is preferably provided in the sloped portion.

With the preferred embodiment set forth above, the at least one opening is provided in the sloped portion, which is located forward of the peak portion. Even if the positions of the upper end portion of the left shock absorber and the upper end portion of the right shock absorber are high, the portion of the front cover that is forward of the peak portion is a sloped portion sloping downward toward the front of the vehicle, thus providing an improved front visibility.

According to another preferred embodiment of the present invention, the upper end portion of the left shock absorber and the upper end portion of the right shock absorber are located so as to be visible when the vehicle is seen from the front of the vehicle.

With the preferred embodiment set forth above, the upper end portion of the left shock absorber and the upper end portion of the right shock absorber are located above at least a portion of the at least one opening of the front cover. Therefore, the front cover is located at a low position while ensuring a good stroke for the left shock absorber and the right shock absorber. This ingeniously provides both an improved stroke for the shock absorbers and an improved front visibility.

According to another preferred embodiment of the present invention, the upper end portion of the left shock absorber and the upper end portion of the right shock absorber are located above the at least one opening of the front cover.

With the preferred embodiment set forth above, the upper end portion of the left shock absorber and the upper end portion of the right shock absorber project upward past the at least one opening of the front cover. It is possible to locate the front cover at a low position while locating the upper end portion of the left shock absorber and the upper end portion of the right shock absorber at high positions. This ingeniously provides both an improved stroke for the shock absorbers and an improved front visibility.

According to another preferred embodiment of the present invention, the front cover includes a first front cover member including a first peripheral portion defining a portion of the at least one opening; and a second front cover member including a second peripheral portion defining another portion of the at least one opening, and being attached to the first front cover member.

With the preferred embodiment set forth above, the at least opening does not need to be provided by a single cover member. At least a portion of the at least one opening is provided by assembling together the first front cover member and the second front cover member, and it is therefore possible to easily manufacture the front cover including the at least one opening. It is also possible to maintain the left shock absorber or the right shock absorber by removing only the first front cover member or the second front cover member without having to remove the entire front cover. Thus, it is possible to easily maintain the left shock absorber and the right shock absorber.

According to another preferred embodiment of the present invention, the at least one opening includes a left opening and a right opening located to the right of the left opening. The upper end portion of the left shock absorber is located so as to be visible within the left opening when the vehicle is seen from above. The upper end portion of the right shock absorber is located so as to be visible within the right opening when the vehicle is seen from above.

The upper end portion of the left shock absorber and the upper end portion of the right shock absorber are preferably located so as to be visible within the same opening in the front cover when the vehicle is seen from above. With the preferred embodiment set forth above, however, the upper end portion of the left shock absorber is located so as to be visible within the left opening and the upper end portion of the right shock absorber is located so as to be visible within the right opening when the vehicle is seen from above, allowing the left opening and the right opening to each have a small opening area. Therefore, it is unlikely that an object flies into the front cover through the left opening or the right opening. Also, the front cover has a high rigidity.

According to another preferred embodiment of the present invention, a peripheral portion of the at least one opening of the front cover includes a left peripheral portion located to the left of the upper end portion of the left shock absorber when the vehicle is seen from above, and a right peripheral portion located to the right of the upper end portion of the right shock absorber when the vehicle is seen from above.

With the preferred embodiment set forth above, the left side of the upper end portion of the left shock absorber is protected by the left peripheral portion of the front cover. The right side of the upper end portion of the right shock absorber is protected by the right peripheral portion of the front cover. Therefore, when a stone or the like, travels toward the vehicle from the left or right of the vehicle while running, the upper end portion of the shock absorber is protected from the stone or the like.

According to another preferred embodiment of the present invention, a perimeter of the at least one opening is closed when the vehicle is seen from above.

With the preferred embodiment set forth above, the front cover has a high rigidity.

According to another preferred embodiment of the present invention, the at least one opening is provided in a front half of the front cover.

With the preferred embodiment set forth above, a sufficient front visibility is ensured.

According to another preferred embodiment of the present invention, when the vehicle is seen from above, an area of the at least one opening is greater than a cross-sectional area of the left shock absorber, and is greater than a cross-sectional area of the right shock absorber.

With the preferred embodiment set forth above, since the opening has a large area, it is possible to more reliably avoid interference between the upper end portion of the left shock absorber and the upper end portion of the right shock absorber and the front cover. Therefore, the positions of the upper end portions of the shock absorbers are sufficiently high, and the position of the front cover is sufficiently low. This ingeniously provides both an improved stroke for the shock absorbers and an improved front visibility.

According to another preferred embodiment of the present invention, the vehicle further includes a left damping force adjuster attached to the left shock absorber to adjust a damping force of the left shock absorber; and a right damping force adjuster attached to the right shock absorber to adjust a damping force of the right shock absorber. At least a portion of the left damping force adjuster and at least a portion of the right damping force adjuster are located above the at least one opening or located so as to be visible through the at least one opening.

With the preferred embodiment set forth above, the left damping force adjuster and the right damping force adjuster are adjustable from outside the front cover. Therefore, the left damping force adjuster and the right damping force adjuster are adjusted easily, thus making it possible to easily adjust the damping forces of the left shock absorber and the right shock absorber.

According to another preferred embodiment of the present invention, the left damping force adjuster is located to the left of the left shock absorber, and the right damping force adjuster is located to the right of the right shock absorber.

With the preferred embodiment set forth above, the left damping force adjuster is easily adjusted from the left side of the vehicle, and the right damping force adjuster is easily adjusted from the right side of the vehicle. Thus, it is possible to easily adjust the damping forces of the left shock absorber and the right shock absorber.

According to another preferred embodiment of the present invention, the left shock absorber includes a left damper and a left spring attached to the left damper, the left damper including a left cylinder and a left piston rod slidably inserted in the left cylinder. The right shock absorber includes a right damper and a right spring attached to the right damper, the right damper including a right cylinder and a right piston rod slidably inserted in the right cylinder. An upper end portion of the left damper and an upper end portion of the right damper define the upper end portion of the left shock absorber and the upper end portion of the right shock absorber, respectively. At least a portion of the left spring and at least a portion of the right spring are located so as to be visible within the at least one opening when the vehicle is seen from above.

With the preferred embodiment set forth above, the left spring and the right spring are unlikely to interfere with the front cover, allowing the position of the front cover to be low. Thus, it is possible to provide an improved front visibility.

According to another preferred embodiment of the present invention, the vehicle further includes a ring-shaped steering handle located in front of one of the plurality of seats to control steering the left front wheel and the right front wheel.

With the preferred embodiment set forth above, the advantageous effects described above are realized with vehicles including a ring-shaped steering handle.

According to another preferred embodiment of the present invention, the vehicle further includes a radiator located under the front cover and rearward of the left shock absorber and the right shock absorber.

With the preferred embodiment set forth above, a space to the rear of the left shock absorber and the right shock absorber are effectively utilized as a space to accommodate the radiator. The radiator is located under the front cover while providing both an improved stroke for the shock absorbers and an improved front visibility.

According to another preferred embodiment of the present invention, a portion of the left shock absorber and a portion of the radiator are located next to each other in a vehicle front-rear direction. A portion of the right shock absorber and another portion of the radiator are located next to each other in the vehicle front-rear direction.

With the preferred embodiment set forth above, as compared with a case where the left shock absorber, the radiator, and the right shock absorber are located next to one another in the vehicle width direction, it is possible to reduce the size of the vehicle in the vehicle width direction. Therefore, it is possible to reduce the size of the vehicle in the vehicle width direction while providing both an improved stroke for the shock absorbers and an improved front visibility.

According to the various preferred embodiments of the present invention, it is possible to provide a vehicle including a plurality of seats located next to each other in the vehicle width direction, with which it is possible to provide both an improved stroke for the shock absorbers of the front wheels and an improved front visibility.

The above and other elements, features, steps, characteristics and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments with reference to the attached drawings.

The left opening 81 and the right opening 82 are preferably provided in a front half of the front cover 20. The front half of the front cover 20, as used herein, refers to a portion of the front cover 20 that is forward of the middle position between a front end 20A and a rear end 20B of the front cover 20 in the vehicle front-rear direction.

The opening 83 is provided in the second front cover member 72. The opening 84 is defined by the third front cover member 73 and the fourth front cover member 74. The opening 85 is defined by the fourth front cover member 74 and the fifth front cover member 75. The opening 86 is defined by the fifth front cover member 75 and the sixth front cover member 76. Note that the openings 83, 84, 85, and 86 are not always necessary, and may be omitted.

The left opening 81 and the right opening 82 are each an opening having a large area, unlike openings through which screws and bolts are passed. The area of the left opening 81 when the vehicle is seen from above is greater than the cross-sectional area of the left shock absorber 17. The area of the right opening 82 when the vehicle is seen from above is greater than the cross-sectional area of the right shock absorber 18. Note that the cross-sectional area of the left shock absorber 17 varies between different positions along the left shock absorber 17. The cross-sectional area of the left cylinder 42 is greater than the cross-sectional area of the left piston rod 43. Here, the area of the left opening 81 when the vehicle is seen from above is greater than the cross-sectional area of the left cylinder 42. The area of the left opening 81 when the vehicle is seen from above is greater than a maximum value of the cross-sectional area of the left shock absorber 17. At the same time, the area of the right opening 82 when the vehicle is seen from above is greater than the cross-sectional area of the right shock absorber 18. The area of the right opening 82 when the vehicle is seen from above is greater than the cross-sectional area of the right cylinder 52. The area of the right opening 82 when the vehicle is seen from above is greater than a maximum value of the cross-sectional area of the right shock absorber 18. Note, however, that there is no particular limitation on the area of the left opening 81 and the right opening 82.

As shown in FIG. 3, when the vehicle is seen from above, at least a portion of the left shock absorber 17 is visible within the left opening 81, and at least a portion of the right shock absorber 18 is visible within the right opening 82. Here, the upper end portion 17A of the left shock absorber 17 is located so as to be visible within the left opening 81 when the vehicle is seen from above. A portion of the left spring 41 is located so as to be visible within the left opening 81 when the vehicle is seen from above. The upper end portion 18A of the right shock absorber 18 is located so as to be visible within the right opening 82 when the vehicle is seen from above. A portion of the right spring 51 is located so as to be visible within the right opening 82 when the vehicle is seen from above.

The front cover 20 surrounds the left side of the left shock absorber 17 and surrounds the right side of the right shock absorber 18 when the vehicle is seen from above. The peripheral portion of the left opening 81 of the front cover 20 includes a left peripheral portion 81L, which is located to the left of the upper end portion 17A of the left shock absorber 17 when the vehicle is seen from above. The left side of the upper end portion 17A of the left shock absorber 17 is protected by the left peripheral portion 81L of the front cover 20. The peripheral portion of the right opening 82 of the front cover 20 includes a right peripheral portion 82R, which is located to the right of the upper end portion 18A of the right shock absorber 18 when the vehicle is seen from above. The right side of the upper end portion 18A of the right shock absorber 18 is protected by the right peripheral portion 82R of the front cover 20.

As shown in FIG. 2, even though the ROV 1 includes the front cover 20, the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18 are visible when the vehicle is seen from the front.

While the upper end portion 17A of the left shock absorber 17 is preferably located above the left opening 81 in the present preferred embodiment, as shown in FIG. 2, the upper end portion 17A of the left shock absorber 17 may be located below the left opening 81. The upper end portion 17A of the left shock absorber 17 projects past the left opening 81. Although not shown in the figures, the upper end portion 17A of the left shock absorber 17 is located above the peripheral portion of the left opening 81 of the front cover 20, along a vertical cross section extending in the vehicle width direction while passing through the upper end portion 17A of the left shock absorber 17. Similarly, while the upper end portion 18A of the right shock absorber 18 is preferably located above the right opening 82 in the present preferred embodiment, the upper end portion 18A of the right shock absorber 18 may be located below the right opening 82. The upper end portion 18A of the right shock absorber 18 projects past the right opening 82. The upper end portion 18A of the right shock absorber 18 is located above the peripheral portion of the right opening 82 of the front cover 20, along a vertical cross section extending in the vehicle width direction while passing through the upper end portion 18A of the right shock absorber 18.

As shown in FIGS. 8 and 9, at least a portion of the left damping force adjuster 61 is located so as to be visible through the left opening 81. At least a portion of the left damping force adjuster 61 may be located so as to be visible through the left opening 81 when the vehicle is seen from above, and may be located so as to be visible through the left opening 81 when seen from the front, diagonally from the front, diagonally from the side, or diagonally from the rear. In the present preferred embodiment, a portion of the left damping force adjuster 61 is located over the left opening 81. The control 63 of the left damping force adjuster 61 preferably is located over the left opening 81. Note, however, that the control 63 may be located so as to be visible through the left opening 81. For example, the control 63 may be located under the left opening 81. When the control 63 is located over the left opening 81, a passenger can easily operate the control 63. Also, where the control 63 is located so as to be visible through the left opening 81, a passenger can easily operate the control 63 through the left opening 81. For example, a passenger can put in his/her hand or a tool through the left opening 81, and operate the control 63 of the left damping force adjuster 61 by using the hand or tool through the left opening 81.

The above description similarly applies to the right damping force adjuster 62. That is, at least a portion of the right damping force adjuster 62 is located so as to be visible through the right opening 82. At least a portion of the right damping force adjuster 62 is located so as to be visible through the right opening 82 when the vehicle is seen from above, and may be located so as to be visible through the right opening 82 when seen from the front, diagonally from the front, diagonally from the side, or diagonally from the rear. A portion of the right damping force adjuster 62 is located over the right opening 82. The control 63 of the right damping force adjuster 62 is located over the right opening 82 . Note, however, that the control 63 of the right damping force adjuster 62 may be located so as to be visible through the right opening 82. A passenger can easily operate the control 63 of the right damping force adjuster 62.

As described above, with the ROV 1 of the present preferred embodiment, the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18 are located so as to be visible within the left opening 81 and the right opening 82, respectively, of the front cover 20 when the vehicle is seen from above. Even if the positions of the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18 are high, or the position of the front cover 20 is low, it is possible to prevent the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18 from interfering with the front cover 20. Therefore, the positions of the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18 are raised to provide an improved stroke for the left shock absorber 17 and the right shock absorber 18. Moreover, the position of the front cover 20 is allowed to be low, thus giving a better front view for passengers seated in the seats 11 and 12. That is, it is possible to improve the front visibility of the ROV 1. Thus, with the ROV 1 of the present preferred embodiment, it is possible to provide an improved stroke for the left shock absorber 17 and the right shock absorber 18 and to also provide an improved front visibility.

With the ROV 1, the peak portion 78 of the front cover 20 is located rearward of the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18, as shown in FIG. 1. The left opening 81 and the right opening 82 are provided in the sloped portion 77 of the front cover 20, and the peak portion 78 is located rearward of the left opening 81 and the right opening 82. Even if the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18 are located at high positions, it is possible to provide an improved front visibility because the sloped portion 77 of the front cover 20, forward of the peak portion 78, slopes downward to the front of the vehicle.

With the ROV 1, as shown in FIG. 2, the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18 are located so as to be visible when the vehicle is seen from the front. The upper end portion 17A of the left shock absorber 17 is located above at least a front portion of the left opening 81, and the upper end portion 18A of the right shock absorber 18 is located above at least a front portion of the right opening 82. Therefore, it is possible to locate the front cover 20 at a lower position and to provide an improved stroke for the left shock absorber 17 and the right shock absorber 18. This ingeniously provides both an improved stroke for the left shock absorber 17 and the right shock absorber 18 and an improved front visibility.

Particularly, with the ROV 1 of the present preferred embodiment, the upper end portion 17A of the left shock absorber 17 is located above the left opening 81, and the upper end portion 18A of the right shock absorber 18 is located above the right opening 82. That is, the upper end portion 17A of the left shock absorber 17 projects past the left opening 81, and the upper end portion 18A of the right shock absorber 18 projects past the right opening 82. Therefore, it is possible to locate the front cover 20 at a lower position while locating the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18 at higher positions. This ingeniously provides both an improved stroke for the left shock absorber 17 and the right shock absorber 18 and an improved front visibility.

With the ROV 1, as shown in FIG. 3, the front cover 20 includes the first front cover member 71 including the first peripheral portion 81 a defining a portion of the left opening 81, and the second front cover member 72 including the second peripheral portion 81 b defining another portion of the left opening 81. Similarly, the first front cover member 71 includes the first peripheral portion 82 a defining a portion of the right opening 82, and the second front cover member 72 includes the second peripheral portion 82 b defining another portion of the right opening 82. In the present preferred embodiment, the left opening 81 and the right opening 82 do not need to be a single member. Therefore, it is possible to easily manufacture the front cover 20 including the left opening 81 and the right opening 82. It is also possible to maintain the left shock absorber 17 and the right shock absorber 18 by removing only the second front cover member 72, for example, without having to remove the first front cover member 71. Thus, it is possible to easily maintain the left shock absorber 17 and the right shock absorber 18.

In the present preferred embodiment, the left opening 81 and the right opening 82 are preferably separate from each other. Note, however, that the left opening 81 and the right opening 82 maybe integral with each other. That is, the front cover 20 may include therein a single opening including the left opening 81 and the right opening 82 (hereinafter referred to as a “large opening”). In such a case, the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18 are located so as to be visible within the large opening when the vehicle is seen from above.

In the present preferred embodiment, since the left opening 81 and the right opening 82 are preferably separate from each other, the area of each of the left opening 81 and the right opening 82 is smaller than the area of the large opening. Therefore, it is unlikely that a large object (e.g., a stone) can move into the front cover 20 through the left opening 81 or the right opening 82 while the ROV 1 is running. It is also easy to ensure a desirable rigidity of the front cover 20.

According to the present preferred embodiment, the front cover 20 includes the left peripheral portion 81L located to the left of the upper end portion 17A of the left shock absorber 17 when the vehicle is seen from above, and the right peripheral portion 82R located to the right of the upper end portion 18A of the right shock absorber 18 when the vehicle is seen from above. The upper end portion 17A of the left shock absorber 17 is protected by the left peripheral portion 81L of the front cover 20, and the upper end portion 18A of the right shock absorber 18 is protected by the right peripheral portion 82R of the front cover 20. Therefore, when a stone or the like, moves toward the vehicle from the left or right while the vehicle is running, the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18 are protected from the stone or the like.

Each of the left opening 81 and the right opening 82 may be an opening whose perimeter is partially left open, but the openings preferably have a perimeter that is closed. Despite the left opening 81 and the right opening 82 being provided in the front cover 20, it is possible to significantly reduce or prevent a decrease in rigidity of the front cover 20. According to the present preferred embodiment, the front cover 20 has a high rigidity.

While the left opening 81 and the right opening 82 are preferably provided in the front half of the front cover 20 in the present preferred embodiment, there is no particular limitation on the positions of the left opening 81 and the right opening 82. Thus, a sufficient level of front visibility is ensured. For example, even if the upper end portion 17A of the left shock absorber 17 projects upward past the left opening 81 and the upper end portion 18A of the right shock absorber 18 projects upward past the right opening 82, it is possible to ensure a good front visibility.

In the present preferred embodiment, since the front cover 20 includes the sloped portion 77 sloping downward to the front of the vehicle, the front half of the front cover 20 is located at a low position. However, according to the present preferred embodiment, the upper end portion 17A of the left shock absorber 17 and the upper end portion 18A of the right shock absorber 18 are located at high positions while locating the front cover 20 at a low position, as described above. Therefore, the left shock absorber 17 and the right shock absorber 18 are located under the front half of the front cover 20.

According to the present preferred embodiment, when the vehicle is seen from above, the area of the left opening 81 is greater than the cross-sectional area of the left shock absorber 17, and the area of the right opening 82 is greater than the cross-sectional area of the right shock absorber 18. According to the present preferred embodiment, the left opening 81 and the right opening 82 each have a large area. Therefore, it is possible to more reliably avoid interference between the upper end portion 17A of the left shock absorber 17 and the front cover 20, and it is possible to more reliably avoid interference between the upper end portion 18A of the right shock absorber 18 and the front cover 20. This ingeniously provides both an improved stroke for the left shock absorber 17 and the right shock absorber 18 and an improved front visibility.

According to the present preferred embodiment, at least a portion of the left damping force adjuster 61 is located above the left opening 81, and at least a portion of the right damping force adjuster 62 is located above the right opening 82. The left damping force adjuster 61 is able to be operated from outside the front cover 20, and the right damping force adjuster 62 is able to be operated from outside the front cover 20. Therefore, the left damping force adjuster 61 and the right damping force adjuster 62 are operated easily, i.e., the damping forces of the left shock absorber 17 and the right shock absorber 18 are adjusted easily. Note that at least a portion of the left damping force adjuster 61 may be located so as to be visible through the left opening 81, and at least a portion of the right damping force adjuster 62 may be located so as to be visible through the right opening 82. Even then, the left damping force adjuster 61 is able to be operated from outside the front cover 20 through the left opening 81, and the right damping force adjuster 62 is able to be operated from outside the front cover 20 through the right opening 82.

According to the present preferred embodiment, the left damping force adjuster 61 is located to the left of the left shock absorber 17, and the right damping force adjuster 62 is located to the right of the right shock absorber 18. Since the left damping force adjuster 61 is located relatively far to the left, the left damping force adjuster 61 is easily operated from the left side of the ROV 1. Since the right damping force adjuster 62 is located relatively far to the right, the right damping force adjuster 62 is easily operated from the right side of the ROV 1. Thus, it is possible to easily adjust the damping forces of the left shock absorber 17 and the right shock absorber 18.

According to the present preferred embodiment, a portion of the left spring 41 of the left shock absorber 17 is located so as to be visible within the left opening 81 when the vehicle is seen from above. A portion of the right spring 51 of the right shock absorber 18 is located so as to be visible within the right opening 82 when the vehicle is seen from above. Therefore, the left spring 41 and the front cover 20 are unlikely to interfere with each other, and the right spring 51 and the front cover 20 are unlikely to interfere with each other. Thus, the position of the front cover 20 is allowed to be low. Therefore, it is possible to provide an improved front visibility.

According to the present preferred embodiment, the radiator 68 is located under the front cover 20 and rearward of the left shock absorber 17 and the right shock absorber 18. Therefore, a space that is under the front cover 20 and rearward of the left shock absorber 17 and the right shock absorber 18 is effectively utilized as a space to install the radiator 68. According to the present preferred embodiment, the radiator 68 is located under the front cover 20 while providing both an improved stroke for the left shock absorber 17 and the right shock absorber 18 and an improved front visibility, thus enabling a reduction in the size of the ROV 1.

According to the present preferred embodiment, a portion of the left shock absorber 17 and a portion of the radiator 68 are located next to each other in the vehicle front-rear direction, and a portion of the right shock absorber 18 and a portion of the radiator 68 are located next to each other in the vehicle front-rear direction. Therefore, as compared with a case where the left shock absorber 17, the radiator 68, and the right shock absorber 18 are located next to one another in the vehicle width direction, it is possible to reduce the size of the ROV 1 in the vehicle width direction. Therefore, it is possible to reduce the size of the ROV 1 in the vehicle width direction while providing both an improved stroke for the left shock absorber 17 and the right shock absorber 18 and an improved front visibility.

The preferred embodiments described above are merely exemplary preferred embodiments of the present invention, and the present invention can be carried out in various other preferred embodiments. For example, as shown in FIG. 10, the left damping force adjuster 61 may be located on the rear of the left shock absorber 17, and the right damping force adjuster 62 may be located on the rear of the right shock absorber 18. At least a portion (e.g., the control 63) of the left damping force adjuster 61 may be located so as to be visible within the left opening 81 when the vehicle is seen from above. At least a portion (e.g., the control 63) of the right damping force adjuster 62 may be located so as to be visible within the right opening 82 when the vehicle is seen from above.
